PURPOSE:To indicate residual quantity of roll paper and prevent it from getting loose through pressing it by movably providing an indicator, used also as a roll paper pressing member, on a peep window with a dial gauge formed on a flange for holding roll paper. CONSTITUTION:When forms are drawn ut from a roll paper 2 and the roll paper 2 is reduced in the diameter, an indicator which is used also as a roll paper pressing member follows to move towards the center of a flange 4 due to force of a coil spring 17. Accordingly, a roll paper pressing part 14 presses down the surface of said paper 2 by means of the force corresponding to the tensile force of the coil spring 17, and further, both ends of the pressing part 14 come in contact with the surface of the roll paper 2 due to elasticity of the arched roll paper pressing part 14 itself. Because of this, even if the roll paper 2 is taken out together with the holder and left as it is in a predetermined depository, the forms do not get loose. Further, residual quantity of the removed roll paper 2 can be easily and accurately grasped by reading a dial gauge 12 shown by an indicator 15. |
